Description of the issue:
Mouse/kbd response is delayed for typically 1-2 seconds if browser is left idling for 15-30 seconds while I’m reading the current paragraph and then scroll down further. Delay applies to both keyboard arrow buttons and mouse. Problem does not occur in other browsers. Disabling any one GPU and running only on single GPU resolves the problem.
Steps to Reproduce (add as many as necessary): 1. Open any page in Brave and scroll down the page with short pauses in between.
Actual Result: scrolling is delayed shortly.
Expected result: immediate response from mouse or keyboard input.
Reproduces how often: always
Brave Version(about:brave): 1.28.105 Chromium: 92.0.4515.131 (Official version) (64 bits)
Reproducible on current live release (yes/no): yes
I’m using a ASUS N56JR-S4075H notebook with dual GPU, Nvidia GTX760M and Intel 4600. Running Windows 10 (21H1) 19043.1165. Latest drivers for both GPU.
I guess there is some kind of momentary conflict in Brave or Windows about what GPU to engage when scrolling. The scrolling delay is remedied if I disable any one of the GPU:s (in device manager) and run Windows on only the Intel or Nvidia GPU.
However, screen brightness adjustment and suspend is not available when disabling the Intel GPU so that is not an option. Would be nice to be able to use the Nvidia GPU. I can provide more config and diagnostic info if needed. Thanks.
